两种北虫草硒含量的比较

Comparison of the Selenium Components between Two Cultivated Cordyceps

目的:比较富硒北虫草和普通北虫草的总硒含量、无机硒含量和有机硒含量。方法:采用紫外分光光度法测定富硒北虫草和普通北虫草的总硒含量和无机硒含量,然后通过计算得出有机硒含量。结果:富硒北虫草中总硒含量高于普通北虫草70倍左右,而有机硒含量则大约是普通北虫草的100倍,且富硒北虫草中有机硒含量为总硒含量的97%左右。结论:鞍山华宇生物科技有限公司开发的富硒北虫草中有机硒的含量明显高于普通北虫草,具有良好的使用前景。

Objective： To investigate contents of the total selenium,Inorganic selenium and organic selenium between the Selenium-rich Cordyceps and ordinary Cordyceps.Methods： UV spectrophotometry was used to measure the contents of the total selenium,Inorganic selenium,then we calculated to get the contents of organic selenium between these two kinds of Cordyceps.Results： The contents of the total selenium in Selenium-rich Cordyceps is 70 times as the ordinary,the contents of organic selenium is about 100 times as the ordi-nary,and about 97% of the the total selenium in Selenium-rich Cordyceps.Conclusion： Contents of organic selenium in selenium-rich Cordyceps developed by An San Hua-Yu Biotechnology Co.,Ltd is higher significantly than it in the ordinary Cordyceps.It suggested that the Selenium-rich Cordyceps has good value in future.
